Product Description
A sandwich panel is an ingenious construction consisting of three layers: a lightweight core material nestled between two thin but sturdy steel skin layers. This innovative design offers superb mechanical performance while keeping the weight to a bare minimum. The exceptional rigidity of a sandwich panel is attributed to the harmonious interaction of its components under a flexural load. The core handles shear loads and creates spacing between the skins, which experience in-plane stresses; one in tension, the other in compression. For comprehensive insights into sandwich panel structures, various core types, and their potential for weight savings, please refer to the following reference.
1) Surface sheet:
Typically, the surface sheet of PUR or PIR sandwich panels features PPGI or PPGL steel color-coated sheets. PPGI denotes pre-painted galvanized steel, while PPGL refers to pre-painted Al-Zn coated steel. For coating preferences, you may opt for PE, PVDF, HDP, SMP, etc. Our esteemed strategic partners include Bluescope, Bao-steel, Shougang steel, Guanzhou steel, Yieh Phui steel, Xinyu steel, and more.
2) Polyurethane core material
Our polyurethane core materials are sourced through strategic collaborations with industry leaders such as Huntsman and WANHUA.
The Polyurethane Sandwich Panel, also known simply as the PU Sandwich Panel, features a top and bottom sheet crafted from galvanized and pre-painted steel, with a core of five-component polyurethane glue, meticulously formed through heating, foaming, and laminating. Renowned for its unparalleled heat and sound insulation, polyurethane significantly reduces heat transmission between interior and exterior environments, optimizing the efficiency of freezing and refrigeration systems. This innovative thermal insulation solution offers cost-effective construction options, with panels available in diverse specifications to suit various sites and projects.
The PU Sandwich Panel, technically known as the Polyurethane Sandwich Panel, comprises two layers of durable, weatherproof colored steel sheets, encasing a layer of hard polyurethane foam. It's ideally suited for extensive applications, such as large factory buildings, storage facilities, exhibition halls, gymnasiums, cold storage, and purification workshops. These panels stand out for their heat insulation, load-bearing capability, weather resistance, vibrant colors, and aesthetic appeal.
Within the PU Sandwich Panels, polyurethane foam is sandwiched between two tough outer skins, earning its moniker. As committed manufacturers, we offer reliable PU sandwich panels in an array of configurations. These dual layers come in profiles made from zinc-coated, galvanized steel, embossed aluminum, stainless steel, or alternative material sheets.
Our company currently offers a diverse range of PU sandwich panels to satisfy the unique requirements of varied customers and markets.
We have three joint ways for PU sandwich wall panels;
